Gateway is software placed in the router. Its function is protocol translation. When we need to connect two networks based on different protocols, then gateway is used by default. It acts as an entrance To see the default gateway of your system in cmd (command prompt), type "ipconfig." It shows the default gateway.

The easiest way is to sign up for the service at a site There you can sign up for an account install a software package on the computer you want to access and leave it on. Then you can access the computer from anyplace with broad band internet or better.

Connect the primary, or first, computer to the printer. This is done traditionally with a printer cable linking the primary computer to the printer. If this is the first time the computer is hooked up to the printer, be sure to follow the manufacturer's instructions for installation and setup.

Change the settings on the primary computer to allow sharing of the printer. Go through the control panel menu option, and select printers. Right-click on the printer selection and choose "Share printer." You are now able to share the printer with any other computers on your network.

Connect the secondary computer to the printer. Access the shared printer option from the secondary computer. Select "network neighborhood" and locate the primary computer. Double-click on the primary computer, and the shared resources will become available. Double-click on the printer. You can now utilize the printer from both computers.

Print sharing has become popular in many home networks primarily because it reduces the cost in implementing networking environments as well as maximizing the potential uses of network resources. The process of hooking two computers to a single printer is very much different from connecting two printers to a single computer because unlike computer systems, printing devices normally only have one communication port that can host a connection. To achieve the task of connecting two computers to a single printer, other devices would have to come into the picture to serve as the host for the printer and provide the underlying communication layer for all devices trying to make use of its printing functionality. The Operating System running on both machines that want to make use of the printing device must also support networking and printer sharing features in order to make this task feasible.

Materials Needed:

- Router

- Ethernet cable

- USB switch

- crossover cable

- network card

- print server

- Operating System that supports printer sharing

Step 1

One of the easiest options to share a printer on networked machines is to connect and install it in one of the machines. Simply click on the 'Start' button and choose the 'Control Panel' category.

Step 2

Select the 'Printer and Faxes' option and click on the 'Add a Printer' task. This will bring up the printer installation page. Make sure to install the printer hardware as a local printer. Follow the prompts to complete the installation process.

Step 3

When completely installed, click on the 'Start' button and select the 'Printer and Faxes' category. The icon for the newly installed printer should be there already. Right click on the icon and select sharing.

Step 4

Provide a shared name for the printing device and click on the 'OK' button.

Step 5

On the other computer, repeat Step 1 to Step 2 but this time, choose the network printer option. Type in the name of the printer and follow the prompts. Install the device driver when prompted to do so.

Step 6

A variation of this method which eliminates the use of a router device is to connect the two machines using a crossover cable. Simply insert one end into the NIC of the machine and repeat the process for the other computer.

Step 7

Both machines must be running at least Microsoft Windows XP to allow for the automatic detection of the network connection. This procedure basically functions the same way as a network environment but is limited to two machines and does not require a router.

Step 8

An alternative to this setup is to install a Print Server which will host the printer hardware and connect directly to the network router. In this method, simply connect the printer to the printer server.

Step 9

Proceed by connecting the print server to the network router which will allow the printer hardware to be detected in the network environment as a standalone device. To print using this method, simply use the IP address assigned to the printing device.

Step 10

Another possible solution is to use switching devices. These types of hardware became popular when printers were hosted using parallel and serial cable connections. For USB-based machines, a USB Switch box may be used. Connect the printer directly to the box using the USB cable.

Step 11

Connect the USB cable from each computer to the respective USB ports on the switching device. To use the printer for computer A, simply set the switch to A and do the same for B. In this method, no additional installation is required. All data switching and handling activities are done by the hardware switch.

Duplex is a way devices like computer talk to each other. Half Duplex is only sending the information one time and hoping the information gets to the other end in a complete form. Full Duplex is sending a short piece of the message to the other end and waiting to tell if it is properly received before sending the next small piece of information.

Power off the server and change the NVRAM Jumper

A firewall router

Your IP is your "Internet Protocol" address. It is a way of identifying your computer system in the network of computers we call the internet. When you pay an isp to link you into the system, they will probably give you a modem, and it will have an IP address to communicate with the network. You can see what that address is by going to whatismyip.com.

Your computer also has an internal network IP if it is connected to a router which the router uses to make sure the different computers requesting web pages and the like through it, get what they asked for.

A wireless router resembles a flat plastic box with different lights indicating various states of connection. Some wireless routers have small antennae to help them transmit the WiFi over a certain radius.

In the IP address 177.100.18.4, the network portion is determined by the subnet mask. Without knowing the subnet mask, it is impossible to accurately determine the network portion. The network portion is used to identify the specific network to which the IP address belongs, helping in routing and communication between devices.

Twisted pair wiring is a digital signal.

Coaxial cable is an analog signal.

Firstly, most modern laptops already have an internal wireless card installed. For other similar devices, which are portable and battery powered, they may or may not include a wireless card, however. In that case, you would have to check the specifications for that device and check if a wireless card can be possibly installed. Most desktops do not have their own wireless card installed by default, but you may purchase either an internal or external wireless card for the desktop.

Most computers have ports that allow human interface devices, such as keyboards and mouses to be connected. Laptops, for example, may already have a touchpad and a keyboard built in. If there are no human interface devices, you may get a wireless keyboard and/or mouse, which use radio frequencies or Bluetooth wireless.

Lastly, if you want online access, you will need a Wi-Fi or WiMAX card (http://en.wikipedia.org/wiki/Wi-Fi for more information) to connect to a wireless network with an Internet connection.

* Manually set up a route in a dormant manner.

* Stable.

* Has no impact made by traffic and transmission failures.

* Creates no traffic derived from routing protocols.

= dynamic routing: =

* Automatically sets up a route.

* Can respond to the changes of the network.

* Can automatically select the optimized route.

* Can automatically select the backup route.

It dependence on what kind of connection you are using to bring internet in your house. If you are using a land line or cable, your wireless will work just fine. If you get your internet through a cell phone you might not be able to connect if the signal is not strong enough.

Power on the router and press the reset switch for 30 second which is located bottom of the router, after restart the router and it will asked u to give the user name and password for use. By default the user name : Admin & the password : Admin.

TCP IP is the protocol of choice when it comes to networking due to its ability to confirm the receipt of packets by the intended destination. As such, this protocol in email and web browsing.

Now if you mean how does it catch a attacker:

If a large amount of packets are being sent through ports that are above normal, or above the standards sent, it would assume its a attacker and posibly close the port until future action is stated.

If you mean how a attacker finds a port:

The attacker merely sends multiple small packets to multiple ports and sees which comes with a received message, stating it is a open port prone to attack.

The Switch by paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic tomachine A needs to only be sent to that port and not any of the others. The net result of using a switch over a hub is that most of the network traffic only goes where it needs to rather than to every port. On busy networks this can make the network significantly faster.

Routers switch packets between networks. They are intelligent (typically OSI model layer 3) devices that receive incoming packets inspect their destination (and sometimes source) address, then figure out what is the best path for the packet to take towards its final destination.

Ethernet is the most popular networking technology used in LANs. Fast Ethernet is used to refer to any version of Ethernet that meets or surpasses the 100 Mbps transfer speed.
